I run an older Ranger with two seperate livewells. I use my aereator but it over flows into the bilge. After awhile I am having to hit the bilge switch to discharge the boat. I am wondering if there is a way to makes this all more simple. I have thought about a float switch on the bilge that would automatically discharge. But have also thought of installing a 12v bubbler system that will run continueously. I cannot use additives to my livewell because it will be wasted and dumped.

I have also thought of plumbing the over flow to the outside but am hesitant on cutting another hole in my boat.

When I place a fish in the livewell. I like to let the water run a while, If I get one that isn't feeling good I will leave him alone in a box and pour the water too him. Thus makes it challenging to remember to shut it off.

Can you give me some direction on which way to go? Thanks!

_{I posted this info below on another thread from a couple of weeks ago.  The pure oxygen-injection system described below is scientifically proved to be the best way to maintain oxygen levels in livewells.  This system would be a great fit for your situation.}

 

 

 

_{Without question, the absolute best way to maintain ideal oxygen levels under any condition is the use of an oxygen-injection system (bottle with pure oxygen, regulator, and fine-pore diffusers). The difference here is that we are injecting pure, 100% oxygen, whereas livewell pumps just inject air (21% oxygen). I have been running this system on my boats for the last 3 years (over 40 tournaments) and wouldn’t have it any other way. Detailed info and equipment specs are provided at the link below. $300 will buy all that you need.}

 

_{Because tournaments are so popular and frequent in Texas, Texas Parks and Wildlife Department fisheries biologists have conducted several scientific evaluations of fish care equipment to ensure that tourney anglers have the information to take best care of their fish and minimize tourney-related mortality. I have been involved in each of these evaluations. You can contact either me or the other fisheries biologists listed in the links below with specific questions.}

I have a ranger with dual livewells. Mine discharges out the side for overflow and out the back for drain. Never heard of one that overflows into the boat, maybe you have a hose disconnected? 

 

Does your boat have a recirculation pump? If not, that is where I would start! You can constantly have water moving without having to pump new in.

X2. Maybe since it's an "older model ranger" it doesn't have one.
